The Utility of a Hyperspectral Infrared Imager for Crewed Exploration of
Planetary Bodies
Abstract
Planetary analog simulations are a powerful exercise for understanding
the utility of deployable instruments, their operational protocols, and
the visualization of data products during ExtraVehicular Activities
(EVAs). This paper presents results of a field campaign by the Remote,
In Situ and Synchrotron Studies for Science and Exploration-2 (RISE2)
team to Kilbourne Hole, New Mexico in March/April 2023 to test the
utility of a portable thermal infrared (TIR) hyperspectral imager (HSI)
during four EVA simulations. The HSI provides emitted radiance spectra
from 7 to 14 µm to map composition, which aids in sample selection. Four
pairs of analog astronauts performed a mock EVA at three stations with
field deployable instruments including the HSI. The HSI was found to be
a useful tool for performing reconnaissance observations, field site
documentation, and sample selection for visibly indistinct materials.
From these analog simulations we prioritize two recommendations for use
of HSI in crewed missions. First, HSI-derived data products should be
tailored for the specific science objectives and/or sampling objectives
of the mission to expedite interpretation and decision-making. Second,
pre-EVA reconnaissance using HSI data collected from a remotely operated
rover could further enhance the usability of HSI products.
